The cost of divisions B and C is not estimated for three further purposes
What the document says“the budgetary effects of divisions B and C shall not be estimated--”
Subsection (c) keeps the same effects from being estimated for three purposes: section 251 of the Balanced Budget and Emergency Deficit Control Act of 1985, an allocation to the Committee on Appropriations under section 302(a) of the Congressional Budget Act of 1974, and paragraph (4)(C) of section 3 of the Statutory Pay-As-You-Go Act of 2010, which treats an amount as included in an appropriation Act. It says this notwithstanding Rule 3 of the Budget Scorekeeping Guidelines and section 250(c)(8) of the 1985 Act.
What the document actually says“the budgetary effects of divisions B and C shall not be estimated--”
The cost of divisions B and C is not counted for these three things.
Cost figures feed into several sets of rules. Each one can force a cut or block a bill. This keeps these costs out of all three.
